Abstract (en)
[origin: EP0469700A1] A lubrication system for a scroll machine which, to any extent desired, can utilize the centrifugal forces generated by the orbiting of the orbiting scroll member to influence, either positively or negatively, the flow of fluid in a portion of the lubricant system. This fluid can be either a lubricating oil fed to the thrust bearing for normal lubrication, an oil injection into the intermeshed scrolls to increase sealing and efficiency while attenuating noise, or a venting of vapor from some point in the lubrication system. This is achieved by an oil chamber (110), defined between the top of crank pin (38) and the blind end (112) of hub (68) of orbiting scroll member (64). Chamber (110) communicates with a radially extending passage (114), having intermediate its ends a lubrication port (118) and an oil injection port (119). Oil is supplied through lubrication port (118) to an oil supply groove (120) of a thrust surface (67), as scroll member (64) orbits, when the inertia forces on the oil enhance oil flow in passage (114). <IMAGE>
